7.1 Preparing the installation site
Choose an installation location with sufficient space to transport the unit in and
out of the site.
Do NOT install the unit in places often used as work place. In case of construction
works (e.g. grinding works) where a lot of dust is created, the unit MUST be
covered.
WARNING
The appliance shall be stored in a room without continuously operating ignition
sources (example: open flames, an operating gas appliance or an operating electric
heater).
WARNING
DO NOT reuse refrigerant piping that has been used with any other refrigerant.
Replace the refrigerant pipes or clean thoroughly.
